When three built-in fittings are I shape shaped steel or two web shaped steel, one end of the second built-in fitting and the 3rd built-in fitting is welded to connect respectively with inside the reinforcing bar up and down in two precast beams, and is welded with shear stud at an upper portion thereof; Connect with junction plate between the edge of a wing of the edge of a wing at the first built-in fitting two ends, web respectively and the second built-in fitting, the 3rd built-in fitting external part, web, and fix with high-strength bolt;
When three built-in fittings are truss, truss is spliced by angle steel and batten plate to be made, and is connected between the outside of top and seat angle by batten plate; Be welded with one piece of riser in described two precast beams, one end of described second built-in fitting and the 3rd built-in fitting is welded to connect with the one side of this riser respectively, and the another side of riser is welded with reinforcing bar up and down in two precast beams and straight dowel; Connect with junction plate between angle steel respectively and the second built-in fitting at the first built-in fitting two ends, the angle steel of the 3rd built-in fitting external part, and fix with high-strength bolt.
The syndeton of described prefabricated assembled concrete beam column, is characterized in that: the junction of described first built-in fitting and the second built-in fitting, the 3rd built-in fitting is provided with stirrup.
The syndeton of described prefabricated assembled concrete beam column, is characterized in that: described first built-in fitting welds shear stud.
The invention has the beneficial effects as follows: break away from the cast-in-place old pattern of node, prefabricated post and precast concrete beam are reserved position by the direct assembled connection of high-strength bolt, special built-in fitting is set in addition and solves connection stiffness mutation problems.This connected mode is simple and reliable, economic and practical, and both can meet the overall Aseismic Reliability of system, abandoned again Site Welding, construction operation efficiency, safety are obtained for larger raising.
Also there is following advantage:
Construction rapid and convenient: connects with high-strength bolt and replace welding, construction technology is easy, eliminates welding detection operation, can accelerating construction progress;
Structural system is safe and reliable: nonlinear deformation is concentrated on join domain, and other parts of structure keep elasticity, and the safety of node type of attachment is high.Ultimate bearing capacity of joints and cast-in-place node are quite even better than cast-in-place node, and ductility and energy absorption capability are all better than cast-in-place node;
Adopt shaped steel or angle steel form, reduce rigidity sudden change, improve bearing capacity, shaped steel arranges shear stud, solve steel work and concrete junction shearing resistance problem;
Construct general: than sleeve or slurry anchor connection mode, the present patent application adopts conventional high-strength bolt to connect, and concrete structural system and steel structure connection mode are organically blended, design and construction is comparatively convenient, quality control is also easy to realize with examination, has stronger versatility and promotional value.
